Design and Simulating-calculation of On-line Inspection Locking Device for Packing Sealing

为提高军工产品包装物密封检测工序的测试精度、本质安全性与自动化程度,对某军工包装物密封性在线检测装置锁紧机构进行设计和仿真计算分析。结果表明:在检测压力为0.05 MPa时,采用铜、钢为检测仓与锁紧装置材质,锁紧机构夹持力大于检测箱检测气压产生的向上的力,锁紧装置锁紧力和强度满足要求;锁紧装置的锁紧销与锁紧座的安全系数分别为12.3和7.17,均大于安全系数经验值,强度满足设计要求,能够稳定可靠工作。

In order to improve the testing accuracy,the intrinsic safety and the automatic level of the packing sealing inspection process step of certain military product,a locking device for the online packing sealing inspection has been designed and simulation calculation has been carried out.The results indicate that with an inspection pressure of 0.05 MPa,with copper and steel as the material for the inspection cavity and the locking device,the holding force of the locking device is higher than the force upward generated from the inspection cavity air pressure and the strength of the locking mechanism could meet the requirement.Moreover,the safety coefficient of the locking pin and locking seat of the locking device is respectively 12.3 and 7.17,both higher than the empirical safety coefficient value.It is concluded that the strength of the locking device could meet the design requirement and the locking device could work reliably and stably.
